Mexican Unions Split Over Antitrust Risks in Volaris-Viva Merger

According to reporting by Mexico Business News, labor unions representing aviation workers have voiced concerns that the planned transaction could reduce competition, weaken labor protections and increase market concentration. The publication reported that the proposed deal has prompted disagreement among unions over its potential impact on employees and consumers.

The proposed transaction, announced in late 2025, would combine the holding companies of Volaris and Viva while allowing the two carriers to continue operating under separate brands, management teams and operating certificates, according to company statements previously reported by Mexico Business News and Reuters. The companies have said the structure is intended to preserve each airline’s commercial identity while achieving operational efficiencies.

Competition specialists have cautioned that regulators are likely to closely examine the transaction because the two airlines are Mexico’s dominant ultra-low-cost carriers. Mexico Business News, citing comments by attorney Juan Carlos Machorro in an interview with aviation publication A21, reported that bringing two direct competitors under common ownership would likely attract close antitrust review under Mexico’s competition laws.

The merger proposal remains subject to approval by Mexican and other international competition authorities. Reuters has reported that the combination would create the country’s largest airline group and that regulators are expected to evaluate whether the transaction could lessen competition in the domestic aviation market.

Supporters of the transaction argue that greater scale could improve the airlines’ purchasing power for aircraft and other inputs, while critics contend that increased concentration could ultimately limit consumer choice and affect fares. The publication also reported that labor organizations remain divided over whether the deal would strengthen the industry’s long-term competitiveness or undermine workers’ bargaining power.

If approved, the transaction would represent one of the most significant consolidation moves in Mexico’s aviation industry in recent years and is expected to serve as a major test of the country’s competition authorities as they assess the balance between operational efficiencies and preserving market competition.
